York Peppermint Patties

1 (14−ounce) can Eagle Brand Sweetened Condensed Milk
1 tablespoon peppermint extract
green or red food coloring, optional
6 cups confectioners' sugar
Additional confectioners' sugar
1 − 16 oz. bag semi−sweet chocolate chips

In large mixer bowl, combine Eagle Brand, extract and food coloring if desired. Add 6 cups sugar; beat on low speed until smooth and well blended. Turn mixture onto surface sprinkled with confectioners sugar. Knead lightly to form smooth ball. Shape into 1−inch balls. Place 2 inches apart on wax paper−lined baking sheets. Flatten each ball into a 1 ½−inch patty. Let dry 1 hour or longer; turn over and let dry at least 1 hour.Melt the chocolate chips in a microwave set on high for 2 minutes. Stir halfway through the heating time. Melt thoroughly, but do not overheat. Melting the chocolate chips can also be done using a double−boiler over low heat. With fork, dip each patty into warm chocolate (draw fork lightly across rim of pan to remove excess coating). Invert onto wax paper−lined baking sheets; let stand until firm. Store covered at room temperature or in refrigerator.
